Infinite Renewable Energy Systems Ltd is an amazing company, and they have a new Gas Safe Engineer who just replaced all of the radiators in our home. They are installing our Air Source Heat Pump at the end of May, and I have received pre-approval for the EST Grant Funding. The plumbers, electricians and staff have all been fantastic! 10/10 for service and high quality of work. I would highly recommend them for ASHP, Boiler Upgrades and Heating Services.
